How can one set the output common mode voltage of the DAC of AD9963. The full scale current is (Ifs) 2 mA and does it implies the common mode voltage level is  Ifs/2 * R.   I need to interface the DAC to another module which has the common mode range of 1.5 V. Its written in the data sheet that with TXVDD 3.3 and TXCML 0.5 V the maximum common mode output level can be 1.25 V but its mentioned that the output compliance range for the same setting is 1.7V..  Why is that...
